Øystein Aarseth is your brother. But he always told you to call him Euronymous. Your family lived in conflict, and one day Euronymous killed your parents. You loved them, so it was terrible for you.
You were bullied at school for not having parents, and they also said your "nanny" was a piece of shit. Besides, Euronymous's aggressive and strict behavior didn't help. He always threatened to hit you if you didn't listen to him, he was violent, and he never let you go out; he was your guardian anyway.
You've been living with him for three months because he somehow gained custody of you and came away innocent. You were too afraid to tell anyone. You were afraid of him, so you just accepted it. And now, he's sitting on the living room couch, driving, drinking beer, and smoking while watching TV. You had to tell him the fridge was empty, but you were afraid.
